Thread: 2208 in 284?

Should have the 150s shifting. I'm at 2750 with the eldms 18 inch barrel without pushing hard

I think 2208 is prolly a bit fast for 162s, but it seems to be working well for you.

I use 2213sc with 162 ELD-X. That gives me a very leisurely 2600 fps with 55.5 grains from a factory length T3. It’s a way under max load but very accurate. I could much go faster, but it’s killed everything pretty dead up to 340 yards so far.

Wonder if they still be using 2208 in 2208? I doubt they were using it in 284

Hi bro, The win 760 powder is doing really good on my 284. If I do my part right easy 1/4 inch group at 100m , however, win 760 is temperature sensitive! Same loads, from summer to winter the velocity drop about 4 FPS per degree. Do you use the same load all year round and adjust the velocity data on the ballistic app if shooting long range?

Gone back to 2209 now exclusively and 154ssts/150spbt gamekings

Hi Chief! How’s that rifle (barrel) going?

Well thats what I've been using (2205 and 150gn projectiles.) but this W760 seems to be more accurate in my rifle. I'll let you know what the speed is like when its sorted.

150gr gamekings
154ssts
Needless to say been willing to throw the towel in a few times with the rifle but think I have it sussed now. Has killed more animals than any other rifle I have owned but wasn't shooting tight enough groups, as above you will see i have overcome with ssts shooting consistently sub MOA and that gameking load shooting just over 0.5moa. Shooting over a chrony this week but think I will stick with the gamekings as my go to.

Would assume the gamekings are moving a bit faster than the SSTs given the POI but could be wrong

Good one, I’ve always found the Gamekings easy to tune up as well interestingly enough.

Thought I'd chip in with some results albeit different to AR2208

So my rifle is a T3 7mm-08 reamed out to .284 and cut back to 16 inch with a DPT over barrel suppressor and a Stug carbon fibre stock which I've been running for the past few years and it's accounted for a fear few sika, fallow, reds and now chamois.

My favorite load is 53 gr AR2209 behind a 150 Sierra Game King which will give me 2557 fps and give me great groupings out to 300 mtrs which is the furthest I've tested.

I was running my loads through another chronograph which unbeknown to me was giving me false higher readings until I tried a Labradar so all of the speeds I'll mention below have been tested with a labradar.

I've just taken what I've written from my reloading/note book aswell as any comments I wrote beside them as I rarely keep the actual test targets.

150 gr Sierra Game King (# 1913)
53 gr AR2209 = 2571 fps
54 gr AR2209 = 2616 fps

56 gr RE17 = 2934 fps (a bit hot, back off 1 grain)

140 gr Sierra Pro Hunter
53 gr RE17 = 2693 fps
54 gr RE17 = 2797 fps
55 gr RE17 = 2871 fps

RE17 wasn't producing tight enough groups.

140 gr Nosler Ballistic Tip
54 gr RE17 = 2812 fps
55 gr RE17 = 2894 fps (3/4 inch grouping at 100 mtrs, try again)
56 gr RE17 = 2958 fps

Performance
RE17 gives faster speeds as per the results show and it also gives a heavier recoil where as AR2209 doesn't.

I found the best groups with 150 Sierras was with AR2209 and with 140 Ballistic Tips was RE17

As for projectile performance and I speak from my own experiences is that the power of the 150 gr Sierras have always passed through Sika hinds, Sika stags leaving one hell of a blood trail. On Fallow I found them to not open up as quickly so I always figured a lighter 140 gr projectile would do better.

I did read of a north American hunter who only ever hunted with a .284 win with a 140 gr class projectile. I can't find that article but it was interesting reading as he'd accounted for numerous Elk with the 140's

As I'm now in the south Island I'm toying with the idea of rebarreling to a longer 20 inch barrel but in .284 so I can get more speed with the 150's out to 400 mtrs.

Is there anyone on here with a 20 inch .284 who could share their experiences?

I have the std 22" tikka reamed out by the same Smith who did superdivers. I've had more or less the same groupings, around moa with whatever I've tried. Currently running a mild 51 grains of 2209 behind a 160 Sierra tmk doing 2740. Shoots sub Moa, but not as tight as I like. Going to work up a load for the game king and the Berger 168 and see how i get on.

I am running 2209 for both loads now as opposed to one of each. Think it is 54.5grs of 2209 behind a 150gr gameking which I aim to chrony tomorrow but it is sub MOA and from what I gather a very good killing projectile. Interesting to hear you say you find it passes through sika hinds etc as thought being a sp it would expand a bit

The GK's are a great dependable projectile where I have used 150's in the .284 and 7mm Rem Mag & 120's in 7mm-08's

Like all projectiles you will get projectiles often passing through Sika and Sika hinds leaving a good exit hole out the other side but it's with Fallow which are a lighter animal where I feel they pass through before they've done all their damage as they should.

I think with the Fallow I would choose a faster opening projectile, Ballistic tips are a harder projectile still.

Personally for hunting Sika & Fallow I always found it hard to not use my .223 as they were just bang flops and often I'd fine the projectile nicely mushroomed on the far side under the skin.

My thoughts on the subject was that with the bigger calibres the projectile was still travelling and often right through the animal where a lot of it's energy wasn't being dumped in the animal where as with the .223 all of it's energy was even though I would be shooting the deer in the same spot, crease behind the shoulder.

Yep, have both 20 and 22 in 284s. In fact done two 20 in and load dev for both.
160 TMKs with Superformance giving 2830 - 2850 fps.
145 Speers w 2209 giving 2900+ fps

In 22 in bbl Tikka 2506 donor action Truflite 1:8.5 twist
162 AMAX with RL17 doing 2950 fps, 0.5 moa groups
160 TMKs with Superformance 2900 fps
150 ELDX w RL17 2995 fps
